Abstract
A method for producing crystalline particles including a mixing step of producing a mixed material containing a lead-containing material and an additional material containing lithium and boron and a first firing step of firing the mixed material at a predetermined firing temperature to form polyhedral crystalline particles. The crystalline particles are used to produce a crystallographically oriented ceramic by preparing a template layer having uniform crystal orientation in a predetermined direction by fixing the crystalline particles on a substrate, forming a shaped body including a matrix layer arranged on the template layer, the matrix layer being composed of a mixed material that contains a lead-containing material and an additional material containing lithium and boron, and firing the shaped body.
